Origin
The surname Olbrantz is believed to have originated in Germany during the late Middle Ages. It is thought to be derived from the Old Germanic words "ald" meaning "old" and "brant" meaning "steep hill" or "promontory." This suggests that the name may have initially referred to someone who lived on or near an old, prominent hill or ridge.
The earliest known record of the name Olbrantz dates back to the 14th century, appearing in a historic manuscript from the region of Bavaria. Variations of the spelling at that time included Olbrandtz and Oldebrantz. These early forms further reinforce the connection to the Old Germanic root words.
In the 16th century, the Olbrantz name can be found documented in the town records of Augsburg, a prominent city in southern Germany. This may indicate that the family had established itself in that area by that time period.
One notable bearer of the Olbrantz name was Hans Olbrantz, a German merchant and trader who lived from 1520 to 1588. Records show that he frequently traveled throughout Central Europe, conducting business ventures in cities such as Vienna and Prague.
Another historically significant individual with this surname was Katharina Olbrantz, born in 1612 in the town of Nuremberg. She is mentioned in local church archives as having been a skilled weaver and textile artisan, respected for her intricate tapestry work.
In the 18th century, the Olbrantz surname appears in military records from the Prussian region, suggesting that members of the family may have served in the armed forces during that era of conflict and expansion.
One such figure was Johann Friedrich Olbrantz, born in 1735, who achieved the rank of Major in the Prussian Army and was noted for his service in the Seven Years' War against Austria and its allies.
As the centuries progressed, the Olbrantz name continued to be documented across various parts of Germany, with some bearers also migrating to neighboring countries like Austria, Switzerland, and the Netherlands, carrying the surname with them.
Demographics
Among Census respondents with the surname Olbrantz, the largest self-reported group is White at 88.3%. The next largest groups are Hispanic (5.4%) and Black (3.6%).
The bar chart below shows how Olbrantz bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Olbrantz surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
